Cancer cells in neuroblastoma contain a molecule that breaks down a key energy source for the body's immune cells, leaving them too physically drained to fight the disease, according to new research published in the journal ...

A new way to detect - and perhaps treat - one of the deadliest types of breast cancer has been found. Led by researchers at Boston University School of Medicine (BUSM), the study appears online in Breast Cancer Research.

Overseen by her thesis supervisor and in collaboration with B.C. Cancer Agency scientists, a Simon Fraser University doctoral student is developing a faster, more reliable way to diagnose ovarian cancer.

If it takes more than three trips to the GP to be referred for cancer tests, patients are more likely to be dissatisfied with their overall care, eroding confidence in the doctors and nurses who go on to treat and monitor ...

Researchers have identified a new mechanism that the tumor suppressor protein p53 uses to trigger cell death via apoptosis and have shown how the process could be harnessed to kill cancer cells. St. Jude Children's Research ...

Surgery is required when cancer of the kidney causes a Level III thrombus, or clot, to develop in the major vein leading back to the heart. Traditionally this complicated procedure, inferior vena cava (IVC) thrombectomy, ...

Strange rings of DNA that exist outside chromosomes are distinct to the cell types that mistakenly produced them, researchers have discovered. The finding raises the tantalizing possibility that the rings could be used as ...

Black men in England are at double the lifetime risk of being diagnosed with, and dying from, prostate cancer compared with white men in England, according to research published in the open access journal BMC Medicine.

Cancer Research UK scientists have for the first time identified that there are five distinct types of prostate cancer and found a way to distinguish between them, according to a landmark study published today in EBioMedicine.

With many types of cancers, early detection offers the best hope for survival. However, research into new early-detection screenings, as well as possible interventional radiology and surgical treatments, has been hindered ...

A first-of-its kind prostate 'organoid' grown from human embryonic stem cells has enabled researchers to show that exposure to bisphenol A, a chemical in many plastics, can cause overproduction of prostate stem cells in the ...

Resveratrol, a chemical found in red grapes, is more effective in smaller doses at preventing bowel cancer in mice than high doses, according to new research published today in the journal Science Translational Medicine.

The stem cells in our gut divide so fast that they create a completely new population of epithelial cells every week. But this quick division is also why radiation and chemotherapy wreak havoc on the gastrointestinal systems ...

Cancer /ˈkænsər/ ( listen), known medically as a malignant neoplasm, is a broad group of various diseases, all involving unregulated cell growth. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream. Not all tumors are cancerous. Benign tumors do not grow uncontrollably, do not invade neighboring tissues, and do not spread throughout the body.

Determining what causes cancer is complex. Many things are known to increase the risk of cancer, including tobacco use, certain infections, radiation, lack of physical activity, poor diet and obesity, and environmental pollutants. These can directly damage genes or combine with existing genetic faults within cells to cause the disease. Approximately five to ten percent of cancers are entirely hereditary.

Cancer can be detected in a number of ways, including the presence of certain signs and symptoms, screening tests, or medical imaging. Once a possible cancer is detected it is diagnosed by microscopic examination of a tissue sample. Cancer is usually treated with chemotherapy, radiation therapy and surgery. The chances of surviving the disease vary greatly by the type and location of the cancer and the extent of disease at the start of treatment. While cancer can affect people of all ages, and a few types of cancer are more common in children, the risk of developing cancer generally increases with age. In 2007, cancer caused about 13% of all human deaths worldwide (7.9 million). Rates are rising as more people live to an old age and as mass lifestyle changes occur in the developing world.
